The answer is A. An area where the earth's crust would be expected to be thin would be under the Pacific Ocean. There are two different types of crust: thin oceanic crust that underlies the ocean basins and thicker continental crust that underlies the continents.

Weegy: The asthenosphere is the next layer within the mantle. It has the same chemical composition of the mesosphere but differing physical properties. [ In the asthenosphere, the balance between temperature and pressure is such that rocks have little strength. The rocks in the asthenosphere are weak and easily deformed, like butter or warm tar. The asthenosphere is also known as the "low velocity" zone of the mantle because seismic waves slow down as they pass through it. This property tells us that the asthenosphere is composed of partially molten rock slushlike material consisting of solid particles with liquid occupying spaces in between. Although the asthenosphere represents no more than six percent of the mantle, the mobility of this layer allows the overlaying lithosphere to move.
